SPECIFICATION forming part of Letters patent No. 590,092, dated September 14, 18197. Application filed December 31, 1896. Serial No. 617,597. (No model.)

To aZZ whom it may concern.-

Be it known that we, WILLIAM F. DRAPER I and JAMES II. NORTHROP, of Hopedale, in

the county of l Vorcester and State of Massachusetts, have invented an Improvement in Looms, of which the following description, in

connection with the accompanying drawings,

is a specification, like letters and figures on the drawings representing like parts.

This invention relates more particularly to that class of looms for weaving wherein means are provided for automatically transferring a fresh filling-carrier from a suitable source of supply to the shuttle in the shuttle-box of the lay adjacent said source of supply upon failure of the filling. A loom of this class forms the subject-matter of United States Patent No. 529,940, the filling-carriers being mounted in or carried by a rotatable feeder or hopper so located and operated as to bring the filling-carriers one after another into position to be acted upon by an automaticallyoperated pusher, to transfer a filling-carrier from the feeder to the shuttle, the fresh filling-carrier ejecting the old filling-carrier from the shuttle through a slot in the shuttle-box.

In our present invention we have combined an automatic filling-supplying mechanism 0 with a center fillingdetector of novelconstruction, the latter, however, not being broadly claimed herein, as it forms the subject-matter of another application, Serial No.

614,409, filed December at, 1896, by one of the applicants herein, and we have also provided a novel shuttle-positioning device or feeler to prevent the transferring mechanism from operatin g to transfera filling-carrier if the sh uttle is improperly positioned in the shuttle- 4o boX'or if the shuttle fails to enter therein.

Various features of ourinvention will be hereinafter described in the specification and particularly pointed out in the claims.

Figure 1, in front elevation and centrally 45 broken out, represents a loom embodying our present in vention, the greater part of the breast-beam being omitted. Fig. 2 is a transverse sectional view thereof, taken on the line :1: at, Fig. 1, lookingtoward the right,

Fig. 5 is an enlarged perspective detail of the actuating-hunter for the transferrer. Fig. 6 is an enlarged perspective view of a portion of the sh uttle-box, the shuttle-positionin g device or feeler, and the parts controlled thereby. Fig. 7 is a perspective view, also enlarged, of a portion of the lay with the center filling-detector thereon and the mechanism controlled by the position of said detector; and Figs; 8 to 11 are detail views of portions of the mechanism shown in Fig. 7. V

The loom-frame A, breast-beam A the lay A and its actuating mechanism, the shipper-lever 39 and its notched plate 38 the filling-carrier feeder, comprising, essentially, the connected rotatable plates Ct a, suitably shaped to receive the opposite ends of the filling-carriers Z), the weft-thread-supporting plate 6 rotatable with the feeder, the holder [3 with which the weft end of each carrier is connected, the stud f, the pusher f, mounted thereon and having a projection 21, and the spring 22 to raise the pusher are and may be all as represented in said Patent No. 529,940 referred to, wherein like letters are used to designate like parts. An operating-shaft (1 corresponding to the shaft cl in said patent, is mounted to rock in suitable bearings 011 the lay A said shaft being ex tended beyond the loom side at the right hand, Fig. 1, and having rigidly secured thereto a chute or director It, made, preferably, of sheet metal.

Vhen a filling-carrier is to be transferred to the shuttle S, the rock-shaft d is turned, as will be described, to move said chute h into inclined position below the slotted shut-- tle-box, as shown in Fig. at, to receive the ejected filling-carrier and to direct it into a suitable receptacle, (not shown,) the return of the operating-shaft to normal position moving the chute out of the path of the usual picker-stick.

A spring S, Fig. 1, attached at one end tothe lay and at its other end to a collar 2 on shaft d toward the lay. The upper end of the arm is bent over at b and adapted to move across the raceway of the lay in front of the shuttle-box when the operating-shaft is rocked, as will be described, when the fill ing-detector operates to detect the presence or absence of the filling, the offset 19 forming a shuttle-positioning device or feeler.

If the shuttle S is properly positioned within the shuttle-box, as shown in Fig. 6, the movement of the feelerb is unrestricted, but if the shuttle is improperly positioned to receive a filling-carrier from the feeder it will be engaged by the feeler and will hold the latter from further movement as the rotative movement of the operatingshaft cl is completed, the spring 5 yielding at such time.

A bracket o secured to the lay beyond the shuttle-feeler, has a bearing 0 for a short rock-shaft 0, into the outer end of which is screwed the threaded shank of an adjustable actuator or hunter 0, (shown separately in Fig. 5,) held in adjusted position by a setscrew 6 in the end of the rock-shaft, the actuator or bunter being thus rendered readily adjustable to take up wear and for regulation.

The inner end of the hunter-shaft c has fast thereon an arm 0 provided. with a finger 0 extended into the path of movement of a lug or projection 19 on the shuttle-feeler arm b so that if the shuttle is in proper position to receive a filling-carrier the complete throw of the feeler will cause the projection 19 to engage the finger, swinging the arm 0 and turning the rock-shaft c to bring the actuator or bunter G into position to engage and operate the dog O Fig. 4, the latter being rigidly secured to the pusher f, so that as the lay beats up the pusher will transfer a fillingcarrier from the feeder to the shuttle. If, however, the shuttle is improperly positioned in the shuttle-box, the feeler b will be held thereby from moving far enough to operate the hunter rock-shaft c, as described, and the actuator or bunter C will remain in inoperative position out of range of the dog C as the lay comes forward and the transferring mechanism will remain inoperative.

As it sometimes happens that the shuttle may be in the opposite box when the center fork detects the absence of filling, and inasmuch as the transfer of a filling-carrier at such time would be useless, We have provided means for preventing the transfer of a fillingcarrier from the feeder at such time.

The usual movable binder Z7 is provided with an upturned stop I), Figs. 2, 3, 4, and 6, which is in the path of the bent-over end 0 of the arm 0 when the binder is in, the shuttle-boX being empty, so that even though the feeler b may tend to complete its movement across the shuttle-path and move the hunter G into operative position the stop 6 will engage the end of the arm 0 and prevent rocking of the shaft 0 by engagement of the projection b with the finger 0 so that the hunter will not operate.

The feeler-controllin g spring 5 yields when the feeler is stopped, permitting the operating-shaft d to complete its movement. In the ordinary operation of the loom, however, the shuttle when in the shuttleboX presses the binder Z9 out to move the stop 19 out of the path of the hunter-controlling arm 0 as in Fig. 3, so that the latter may be freely moved, as described, to render the hunter operative, the filling-transferring mechanism being actuated thereby.

The arm 0 is downturned at 0 Figs. 1, 3, and 6, and has a lateral ear cthereon, through which is loosely extended a headed stud 0 attached to the lay, a spring 8 surrounding the stud between its head and the car a", said spring normally acting upon the rock-shaft c to maintain the hunter in inoperative position, the depending end a of the arm resting against the bracket a to limit movement of the rock-shaft by the spring.

IVe have herein shown a center filling-detector with means operated by the movement of the lay and controlled by the position of the filling-detector to rock the operating-shaft d and thereby move the hunter 0 into operative position. Upon failure of the filling the filling-detector will act to bring the fillingtransferring mechanism described into operation and a fresh filling-carrier will be transferred to the shuttle if the latter is properly positioned in the shuttle-box.

Inasmuch as the center filling-detector and the means controlled thereby for rocking the operating-shaft (Z form the subjcot'matter of the other application hereinbefore referred to such parts will not be described herein with such strict detail.

The operating-shaft cZ has a bearing in a bracket F, secured to the lay at substantially the center of the shuttle-raceway, an arm d fast on said shaft, being provided with a roll d to cooperate with a controlling-cam D, shown separately in Fig. 8 and mounted to rock freely on a shaft d, held in the bracket.

When the cam D is rocked in the direction of the arrow 35, Fig. 8, the faces (:1 and d act to swing the arm d first quickly and then more slowly, rotating the operating-shaft 61 against the action of the coiled spring S, Fig. 1, secured at one end of the shaft and fixed at its other end.

The pawl-carriercl is mounted on the shaft d, and it has pivoted thereon a pawl e, having an upturned end e adapted at times to engage a projection 01 on the cam D. The pawl is held in the position shown in Figs. 7 and 9 by a spring siwith its cam-arm 6 against the periphery of the pawl-carrier, the latter being rocked at each movement of the lay by a link 61 jointed at one end to the breastbeam and at its other end pivoted to the foot A of the pawl-carrier. Unless the pawl is turned to bring its upturned end e into engagement with the lug b on the cam D the latter will not be turn ed to rock the operatingshaft.

The lay is transversely recessedat A over which the filling t passes when properly laid, the filling-detector (herein shown as a series of tines m) being pivotally mounted in bearings m on the bracket and adapted to enter the recess A upon failure of the filling.

A crank-pin m 011 a disk m secured to the body of the detector, is connected by a link we to a lever m pivotally mounted on a depending portion of the bracket F and controlled by a spring 3 said lever having a toe m on its inner end to either travel over the exterior of the cam-arm e or to enter between said arm and the peripheryof the pawl-carrier c1 In the latter case the pawl e is moved against the stress of its spring 8 to engage and rock the cam D. The spring 5- tends to depress the toe m and also to depress the detector into the pocket A such tendency being prevented by presence of the filling, the spring only having sufficient force in connection with the small leverage of the link m to move the detector-tines into the depression A unless obstructed 'by even so fragile a thing as the filling. If the filling is present, the toe m will be lifted sufficiently to pass over the arm 6 the curvature of the latter acting to lift the detector from the filling as the lay comes forward to avoid crinkling or straining of said filling.

A stop-pin 90, Fig. 7, enters a notch in the plate m and prevents undue rocking movement of the detector in either direction.

A dog 9, controlled by a spring .9, is pivotally mounted on the pawl-carrier 01 the convexed upper end of the dog being in the path of a projectionm on the lever in back of the fulcrum thereof, so that when the lay is moving back and the loomrunning properly the dog will hold the said lever in position to raise the detector and permit the passage of the shuttle. When the lay is all the way back, the dog releases the lug m and leaves the detector free to be acted upon by its controllingspring to feel for the filling. As the lay moves forward the pawl-carrier 01 is rocked by means of the link 01 connected at one end with the lay and at the other end to the extension (Z of the pawl-carrier (1 and the controlling-spring s of the dog g permits the latter to turn, as in dotted lines, Fig. 9, to wipe under the lug 011 the controlling-lever.

The detector is positively moved toward and to detect the filling, if present, by means of its controlling-spring s and if the filling is present the detector is moved away therefrom as the lay beats up by engagement of the toe m with the exterior of the curved arm 6 When the filling fails, the detector moves into the depression A when the dog releases the controller-lever m and the toe m of the lever will pass between the arm 6 and the pawl-carrier. on its fulcrum as the lay moves forward the toe m then acts to rock the pawl e and move it into position to engage and actuate the controlling device for the spring 5 which acts to positively move the detector to detect the filling. I

If the filling is not laid properly for several picks, the detector will at each pick act, as described, to cause the rocking 0f the shaft d and the operation of the filling-supplying mechanism, the latter, however, only acting, it will be remembered, if the shuttle is properly positioned in the shuttle-box.

The loom in Fig. 1 is herein shown as provided at the left-hand side with takeup mechanism and controlling means therefor operative upon failure of the filling, the opcrating-shaft d being extended across the loom to act upon said controlling means, the same, however, forming no part of this invention.

Our invention is not restricted to the precise construction and arrangement of parts herein shown, as the same may be modified or rearranged in various particulars without departing from the spirit and scope of our invention.
